# 3D Office Upgrade Report

## Executive result
The 3D Office is now a browser-based, JavaScript-powered explorable mystery room. Students can drag with a mouse, swipe with a finger on a tablet, use the mouse wheel, or use keyboard controls to look around and find glowing case markers.

## What was improved
- Clear case marker graphics were added for all six rooms.
- Markers now include visible “TAP CASE” labels so students can identify them as interactive.
- Decorative story art is separated from interactive objects.
- The office behaves more like a small 3D game scene rather than a static webpage section.
- Mission activities remain connected to the implicit learning loop: Notice → Choose → Explain → Reveal.

## Best programming fit
Vanilla JavaScript with HTML Canvas was used. This is the best fit for the current build because it:
- runs locally in a browser;
- works on desktop and tablets;
- avoids dependency failures from external 3D libraries;
- supports mouse, touch, keyboard, and accessible backup buttons;
- keeps the package portable for school/home use.

## Future enhancement path
A later phase could upgrade the office to Three.js/WebGL for real 3D movement, room collision, object inspection, inventory, and animated characters. The current canvas build is the safer production step because it is lightweight, reliable, and easier to maintain.
